radio

The radio category groups together posts that are about complete radios and operating rather than individual circuits—transceivers, receivers, handhelds, SDR rigs, and real‑world operating notes. You’ll find write‑ups on rigs like Curumim, sBitx, ZBitx, Baofeng UV‑5R Mini, uBITX experiences, and other commercial or homebrew radios, often with a strong “how it actually behaves on the bands” focus.
